A dielectric embedded monopole antenna for super wideband applications

A dielectric embedded monopole antenna is proposed for super wideband applications. The antenna is designed become inverted cone in order to expand the bandwidth, and the proposed antenna possesses a method to minimize the monopole antenna by dielectric embedded to lower the height of the antenna. The antenna is practically fabricated and simulated. Measured results show a agreement with simulated results that a 10-dB bandwidth of 126% (5.2-24GHz) is achieved with ratio bandwidth 4.7:1.The prototype achieves good impedance matching, constant gain, stable radiation patterns, and constant group delay over the bandwidth.
